JACOB (3,, SELLERS, OF MARSHFIELD, MISSOURI.

MECHANICAL POWER.

SPECIFICATION forming part of Letters Patent No. 298,628, dated May 13, 1884.

Application filed March 31, 1884. (No model.)

To aZZ whom it may concern Be it known that I, JACOB O. SELLERs, a citizen of the United States, residing at Marshfield, in the county of Webster and State of Missouri, have invented certain new and useful Improvements in Mechanical Powers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specific-ation.

Figure 1 of the drawings is a vertical sectional view of my device, taken on line y 3 Fig. 3. Fig. 2 is a top or plan View of the same, and Fig. 3 is a transverse sectional view.

This invention has relation to mechanical powers; and it consists in the construction and noyel arrangement of, the lateral parallel gear-wheels centered on the same axial line, and having in their opposed faces slot-bearings at right angles to each other, adoublepinion shaft parallel to the axial line of said gear-wheels, and having its pinions respectively engaging said gear-wheels, and a pitman working between the gear-wheels, and and having rollers on its opposite sides line ally distant from each other, and respectively engaging the slots of the gear-wheels, all. as hereinafter set forth.

In the accompanying drawings, the letter A designates the frame-work of the motor, having bearings at B for the journals of the gear-wheels, and at O for the pinion-shafts. The gear-wheels D D are provided. with strong journals E, which extend outward in the same axial line, and are seated in the bearings B. These gear-wheels are parallel to each other, and are separated by an interval, F, which is of sufficient width to receive the pitinan. In the opposed faces, G, of these gear-wheels are made diametric slot-bearings H, which are designed to work at right angles to each other.

K represents the pinion-shaft, having its journal ends seated in bearings O, and carrying the pinions L L, which are placed thereon at the proper distance apart to mesh with the circumferential teeth at of the large gearwheels. By means of these pinions and their connecting shaft the gear-w heels are held in proper relative position, so that their slotbearings are always at right angles to each other.

P indicates the pitman, which is a flat bar extending between the opposed faces of the geanwheels, and moving freely in the inter val between said faces. This pitman is provided with a bearing-roller on each side, and these rollers Z Z are distant from each other lineally less than the length of the radius of either gear-wheel. One of these rollers, near the pitman end, engages the slotway of one of the gear-wheels, while the other roller, which is farther from the pitman end. engages the slotbearing of the opposite gearwheel. The journal of either gear-wheel may be extended to receive a crank or pulley, for the application of power. As the gear wheels are rotated, rapid motion of reciprocation is given to the pitman, which is caused to make two direct movements to each revolution of the geanwheels.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-- The combination, with the lateral parallel gear-wheels centered on the same axial line, and having in their opposed faces s1ot-bearings at right angles to each other, of a doublepinion shaft parallel to the axial line of said gear-wheels, which are respectively engaged by the pinions of said shaft, and a pitman working between said gear-wheels, and having rollers on its opposite sides lineally distant from each other and respectively engaging the slots of the gear-wheels, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
